How Does Kalshi Make Money?

Kalshi makes money primarily by charging a transaction fee on the expected earnings of each contract trade, applied to the taker side of the order book. That is the headline, and the rest of the picture (maker fees on select markets, interest arrangements, market-maker programmes) all sits around that single revenue line. Checked on 28 October 2026 against Kalshi's own fee and help-centre pages.

If you are weighing up whether to trade on Kalshi, the question of how the exchange earns its keep matters for a practical reason. It tells you what you are paying, who you are paying it to, and whether the house is on the other side of your trade. On Kalshi, it is not. The exchange matches buyers and sellers and takes a cut of the flow; your counterparty is another trader, not Kalshi itself. That distinction shapes almost everything else about how the platform works.

The fee on expected earnings, in plain English

Start with the sentence Kalshi itself uses on its help centre: "Kalshi makes money by charging a transaction fee on the expected earnings on the contract." That phrasing is doing real work. The fee is not a flat percentage of your stake. It scales with how much the contract could pay out relative to its current price, which means a trade on a 50-cent contract is charged differently from a trade on a 95-cent one.

The mechanics are set out in Kalshi's fee schedule, which the help centre links at the bottom of its site. Specific numbers belong to that document, not to a secondary summary, so the honest answer to "what will my fee be?" is: open the order ticket, and the exchange shows the fee for that specific order before you confirm. That is where the arithmetic actually lives.

One feature of this model is worth flagging. Because the fee is a function of expected payout rather than a flat spread, trading contracts priced near 50 cents (where uncertainty is highest) carries a different cost profile from trading long-shot or near-certain contracts. New traders often miss this. For a wider walkthrough of the pricing itself, our guide to reading Kalshi odds covers how those cent prices map to implied probabilities.

Maker versus taker: who pays the fee

Here is a subtlety most explainers get wrong. On Kalshi, the trading fee is charged to the taker, the trader whose order crosses the book and executes immediately against someone else's resting order. A maker, by contrast, is a trader who leaves an order sitting on the order book waiting to be matched. In most markets, maker orders are not charged a trading fee at all. You can cancel a resting order with no fee attached; the fee only applies if and when a trade executes.

Some markets do carry maker fees. These are listed explicitly on the fee schedule, and when they apply they are charged at a lower multiplier than the taker fee. The help centre notes that maker fees exist in specific series and that the exact figures live in the schedule itself. If you want the direct comparison across platforms, our Kalshi vs Polymarket fees page lays out the headline numbers side by side.

The practical upshot is this. If you place limit orders that sit on the book and get filled passively, you may pay no trading fee at all on a given order, in markets without maker fees. If you cross the spread to get filled immediately, you pay. That is a meaningful design choice. It rewards traders who provide liquidity and charges those who demand it.

There is no settlement fee

A common misconception, worth clearing up directly. Kalshi does not charge a separate fee when a market settles. You pay the trading fee when you enter the position; if the market resolves in your favour, you receive the full dollar per contract with no additional charge taken out at the end.

Selling before settlement is a different matter. That counts as a new trade in its own right, so the normal taker or maker fee logic applies to the exit order just as it did to the entry. If you buy and hold to resolution, you pay once. If you buy and sell early, you pay for both legs. The exchange is not double-dipping at settlement; it is simply charging for each trade that crosses the book. For more on how resolution actually works, see our guide to market resolution.

Interest flows the other way

Here is the part that surprises people. On the question of interest, Kalshi is not primarily extracting value from idle balances; it is passing interest back to users. The help centre's APY page is explicit: eligible US users earn interest on their cash and open positions, including the collateral behind those positions. The prediction-market rate is a variable rate, shown on Kalshi's APY page, with a $250 average monthly balance requirement.

Interest accrues daily, based on the net value of the portfolio, and is paid monthly. That includes both the cash sitting in the account and the end-of-day portfolio value based on last traded prices. So the collateral locked behind an open YES or NO position is still earning.

The eligibility rules are strict: US users and territories only, with a Social Security Number required to receive interest payments above $10 annually. Rates are variable and can change at any time. None of this is a profit centre for Kalshi in the way the trading fee is; it is a feature pitched at keeping balances on the platform. Whatever interest the exchange earns on its banking arrangements, the user-facing programme pays interest out.

Market makers and the question of who you are trading against

Because Kalshi is an exchange, every trade requires a counterparty. In practice, a significant share of liquidity on any order-book venue comes from professional market makers, firms that quote both sides of a market and profit on the spread between bid and ask. Kalshi has publicly discussed working with market-making firms and runs a Liquidity Incentive Program referenced in its help centre, but the specific commercial arrangements with any individual firm are not spelled out on the pages used for this piece.

What is spelled out is that your counterparty on any given trade is another participant on the book, not Kalshi itself. The exchange does not take the other side. This matters because it means Kalshi has no directional interest in whether YES or NO wins; its revenue comes from the fee on each matched trade regardless of outcome. That is a structurally different business from a sportsbook, where the operator sets the line and books the risk. For a longer treatment, our piece on prediction markets versus traditional bookmakers walks through the difference.

The regulatory layer, and why it shapes the business

Kalshi operates as a CFTC-regulated designated contract market. That status is the reason it can offer event contracts to US retail traders at all, and it is also the reason the fee structure is published the way it is. The federal licence is the moat.

It is also contested at the state level. Several states, including Massachusetts, Michigan, Nevada and Washington, have taken action against Kalshi's sports or elections markets in various forms, and others are in ongoing litigation over the question of whether CFTC oversight preempts state gambling law. The commercial consequence is that Kalshi has to geofence certain products in certain states, which shapes what revenue it can collect from where. For the current legal picture, our guide to Kalshi's state-level legality is the fuller treatment.

None of this changes the core answer to how Kalshi makes money. The revenue model is the per-trade fee. The regulation determines which trades can happen on US soil.

Can you actually make money trading on Kalshi?

The question most readers really want answered. Yes, in the sense that Kalshi is a two-sided exchange where winning trades pay out in full and losing trades do not. Yes also in the sense that interest accrues on balances. But the realistic shape of trader outcomes on prediction markets is sobering, and worth understanding before putting serious money down. Our analysis of who wins and who loses on prediction markets looks at the distribution of profits across traders and finds the pattern you would expect from any speculative market: a small share of participants capture most of the gains.

Kalshi makes money whether individual traders win or lose, because the fee is charged on the trade, not on the outcome. That is the business. Understanding it is step one; deciding whether to participate is step two.

Where iPredicta fits in

iPredicta is a UK-based discovery platform for prediction markets, tracking contracts across Kalshi, Polymarket, Betfair, Matchbook and other venues and surfacing where prices move, where venues disagree, and where the volume is actually flowing. We do not take positions and we are not a broker; the editorial work exists to help readers understand what they are looking at before they click through to a venue. For Kalshi specifically, that means watching how fee changes, state-level rulings and interest-rate adjustments shift the economics of trading there, and writing about it when something actually moves.

Frequently asked questions

How does Kalshi make money?

Kalshi makes money by charging a transaction fee on each trade, applied to the taker side of the order book. The fee is calculated on the expected earnings of the contract rather than as a flat percentage of your stake, and the exact figures live in Kalshi's published fee schedule. Some markets also carry maker fees, charged at a lower multiplier and only when a resting order ultimately executes. There is no separate settlement fee; you pay when you trade, not when the market resolves. Kalshi does not take the other side of your trade, so its revenue is the per-trade fee rather than any directional profit on outcomes. The fee is visible on the order ticket before you confirm.

How to make money on Kalshi?

Traders make money on Kalshi by buying contracts at a price below what they believe the true probability of the outcome to be, and either holding to resolution for a full-dollar payout or selling later at a higher price. Winning trades pay out one dollar per contract after fees; losing trades pay nothing. Realistic returns depend on edge, discipline and fee drag. Interest also accrues on cash and open positions for eligible US users with a qualifying balance, so idle collateral is not completely idle. No strategy is guaranteed, and the distribution of outcomes across traders tends to concentrate gains among a small share of participants, as our analysis of winners and losers on prediction markets lays out.

Can you make money on Kalshi?

Yes, in principle: Kalshi is a two-sided exchange where correct forecasts generate real cash profits and incorrect ones result in real losses. In practice, consistent profitability requires an informational or analytical edge that beats both the market consensus and the trading fee. For eligible US users, interest on cash and open positions adds a small return on prediction-market balances of $250 or more, at a variable rate, shown on Kalshi's APY page. The structural reality is that most casual traders lose money on speculative markets over time; a smaller share consistently profit. Treat Kalshi as a market, not a slot machine, and size positions accordingly.

Does Kalshi make money?

Yes. As a CFTC-regulated exchange, Kalshi generates revenue from the trading fees charged on every matched trade across its order book. The headline source is the taker fee calculated on expected earnings, with maker fees in select series adding a secondary revenue line. Whether the company is profitable overall depends on volume, operating costs, regulatory expenditure and other factors not disclosed on the help-centre pages used for this piece. What is clear is that the exchange collects a fee on every trade regardless of outcome, so trading volume rather than directional risk drives the top line. The business is structurally different from a sportsbook, which books risk on its own balance sheet.

Do people make money on Kalshi?

Some do. Prediction markets, like any speculative venue, show a distribution of outcomes in which a minority of participants capture the majority of profits, and most casual traders break even or lose over time. On Kalshi specifically, winning traders tend to be those with specialist knowledge of the markets they trade, disciplined position sizing and a clear view on where fees eat into expected value. Market makers earn through the bid-ask spread rather than directional calls, which is a different game entirely. For most retail traders, Kalshi is better treated as an engaged forecasting exercise with real money attached than as a reliable income source. Interest on balances adds a small return but will not change that picture.
